Definitions
- the invention relates to dial mechanisms for personal protective equipment, and more specifically the chin straps used in ballistic personal protective helmets.
- the invention particularly relates to a dial mechanism with three gears with lace around gearwheels to provide increased retention, stability, and better adjustability on the wearer's head during use.
- Gear fit and retention systems intend to keep the product on the specific body part during use, maintain fit and comfort while in use, and allow the user to release the gear when desired.
- the dial mechanisms made with different materials, sizes, and shapes, are applied to various products such as sneakers, snow boots, sports equipment, medical equipment, etc. These products mainly wrap and support different body parts such as the head, feet, knees, waist, and wrists.
- the other most commonly applied technique requires an additional attachment part for the assembly.
- the invention comprises of a gearwheel, a lace wrapped around the gearwheel, a body that the gearwheel fits into, a lock that ties up or releases the lace, and attachment parts. Two ends of the lace are fixed with a knot to the inner side of the gearwheel and the lace is wrapped around the gearwheel. The lace is released through holes on opposite sides of the gearwheel. Assembly parts on the lace provide a connection to a chin strap. A clockwise turn of a lock piece wraps up the lace inside the gear and lets the user tension a product like a chin strap. On the other hand, pulling out the lock piece allows the user to unwrap the lace to release the product.
- US Pat. No. 8015625B2 discloses an example of this type of mechanism applied to the adjustment of a bicycle helmet fit.
- the invention mentions an adjustment mechanism, that includes first and second retention members (for example, plastic straps) moving relative to each other, enabling the size of a helmet to be adjusted.
- the adjustment mechanism comprises a gearwheel that is connected to at least one of the retention members and can rotate in two directions to move at least one of the retention elements relative to the other.
- an adjustment mechanism consists of a strap with first and second overlapping parts and the pinion wheel that rotates between teeth inside the groove arranged in the first and second overlapping parts of said strap.
- the document numbered US8370967B2 can be shown as another example of the technique.
- the document relates to an adjustable headband for a helmet.
- the invention mentions an adjustable headband for a helmet that comprises a base, a band, the adjusting wheel, a dial, and a cover.
- the invention introduces a ratchet dial mechanism, which consists of three gearwheels, (two small gearwheels, and the large wheel in the middle of the two small gearwheels) and provides tightening or loosening of the lace by wrapping it on the below part of the small gearwheels by rotating a connected lock on the large gearwheel.
- Another aim of the invention is to facilitate the collection and oscillation of the lace by wrapping the two ends of the lace on two small gearwheels.
- the invention provides a faster loosening or tightening of the lace on each turn of the lock of the ratchet dial mechanism.
- the invention provides a simplified design reducing the craftmanship required and costs in production by eliminating the need for extra assembly parts of the manufacturer by the added design of mounting holes on the body.
- the invention is a ratchet dial mechanism that is located in the adjustment mechanism on the ballistic personal protective equipment and provides the adjustment of the chin straps of the ballistic helmets. It includes,
- Figure 1 represents the exploded view of the ratchet dial mechanism (100) subject to the invention.
- the ratchet dial mechanism (100) in its most basic form consists of; a body (10), a large wheel (20) that rotates clockwise in the center of the body (10), the first pinion wheel (30), and the second pinion wheel (40) associated with both sides of the large gear (20) within the body (10) making rotational movement.
- the mentioned groove holds a large gear (20) in its center groove (11).
- the large gear (20) makes a clockwise rotation movement.
- a first pinion wheel (30) and a second pinion wheel (40) connect to both sides of the large gear (20) in the mentioned groove (11), in contact with the large gear (20).
- the first pinion wheel (30) and the second pinion wheel (40) rotate counterclockwise utilizing force transmitted from the large gear (20).
- Two ends of lace (50) go through the holes located on opposite sides of the body (10).
- One end of the mentioned lace (50) connects to the first pinion wheel (30) with a knot and the other end to the second pinion wheel (40) with a knot.
- the rotational movement of the first pinion wheel (30) and the second pinion wheel (40) tightens the lace (50) by wrapping it around the lower part of the first pinion wheel (30) and the second pinion wheel (40). This movement also results in adjustment of the chin strap (200) on which the ratchet dial mechanism (100) is placed.
- a cover (60) is closed on the body (10) that protects the ratchet dial mechanism (100) from external conditions.
- an internal gear (61) that guides the lock (70).
- the cover (60) and the body(10) come together with a snap-fit mechanism.
- a lock (70) fits inside the internal gear (61) on the cover (60).
- the mentioned lock (70) rotates clockwise and moves in and out in the internal gear (61) for user engagement.
- the mentioned lock (70) interfaces with the large gear (20) in its in position within the internal gear (61).
- the lock (70) transmits the rotational movement to the large gear (20).
- the rotational movement of the large gear (20) transmits equally to the first pinion wheel (30) and the second pinion wheel (40) and pulls the lace (50) around the first pinion wheel (30) and the second pinion wheel (40).
- the user pulls out the lock (70) and releases the lace (50) by breaking the contact between the lock (70) and the large gear(20).
- the chin strap (200) loosens by releasing the lace (50).
